Fixed: ForeignKey admin called deprecated method
Fixed: ForeignKey admin called deprecated method

When using the ForeignKeyAutocompleteAdmin field, the search-as-you-type functionality was calling a method, `models.get_model` that was removed in Django 1.9.

This commit fixes this by importing the django 'apps' model and replacing it with `apps.get_model`.
